9.6 Extended custom functions
For particularly fast handling, the functions of the buttons
1.21, 1.23, 1.24, and 1.3 can be customized to provide im-
mediate access to your most important or frequently needed
menu functions.
To do so, the buttons are first customized by defining which
of the menus' functional groups should be called up with the
quick access function. Immediate access is activated by a long
press on the respective button.
The following functions have been added to the user-defined
button programming options:
_ formatting (formatting memory cards)
_ control element lock
10. Improved lens performance
Lens performance has been improved further.
11. Automatic detection of interchangeable focusing
screen types
Interchangeable focusing screen types (e.g. ground glass with
grid) are detected automatically.
More information about "interchangeable focusing screens"
can be found on page 19 of the camera instructions.
